1. Pole designs conform to ANSI/TIA/EIA-222-F with 1/2” radial ice and to ANSI/TIA-222-G (Class I, Exposure B, Topographic Catagory I ). Design criteria must be verified prior to installation based on site-specific requirements. 2. Embedment depths are based on “Normal” soil (TIA Rev. F) and clay “Presumptive” soil (TIA Rev. G) with aggregate backfill. Actual site soil design parameters must be verified prior to installation.3. For corrosive groundwater and/or soil conditions, ROHN recommends additional corrosion control protection such as concrete backfill, additional protective coating over galvanizing or the installation of sacrificial anodes.4. Embedment depths may require adjustment based on local soil conditions.

1. The above antenna data is intended to assist in the selection of the appropriate ROHN pole. Once the total EPA and sway limit is determined for the antennas, the standard ROHN pole can be selected from the tabulated values. (See example below) 2. Tabulated pole EPA capacities represent the maximum EPA capacity of a pole. The capacity is based on the assumption that 80% of the total EPA is located at the top of the pole and the remaining 20% is located 20 ft. below the top. When all loading is located at the top of the pole, the tabulated EPA capacity must be reduced by 20%. 3. Sway limits are determined under a 50 MPH fastest-mile (Rev. F) or 60 MPH 3-second gust (Rev. G) wind speed. 4. The antenna effective projected areas (EPA) and sway limits provided in the antenna index are guidelines for typical antenna systems. Other values may apply for specific antenna models or for site-specific systems.
2 2
1. Using the antenna index, determine the types of antennas to be installed on the pole.2. Add together the EPA value of all the antennas to be supported.3. Determine the most restrictive sway limit considering all the antennas to be supported. For example, for one 3’ dish with a 3º sway limit and one 1’ flat panel with a 4º sway limit, the sway limit for the pole would be 3º and the required pole EPA capacity would be 13+2=15 ft .4. If all antennas are to be supported at the top of the pole, only 80% of the tabulated EPA capacity shown may be considered when selecting a pole. Alternately, the antenna EPA to be supported may be increased by 25%. For example, the required pole capacity would be 15x1.25=19 ft .5. Using the pole sway limit and the required EPA capacities, the appropriate pole may be determined from the tabulated values. For example, for a 120 ft. pole and a 100 mph 3-sec gust wind speed, a medium pole [P/N: DEP120MA] would be required for an EPA capacity greater than 19 ft for a 3º sway limit.
